Ethereum co-founder Vitalik Buterin has publicly welcomed Sign’s initiative to permit consumer registration with no telephone quantity, characterizing the event as a step towards decreasing dependence on what he termed a “extremely oligopolistic system of chokepoints.” 

In an in depth publish on social media platform X, he outlined a number of sensible benefits of decoupling the encrypted messaging platform from conventional phone infrastructure, together with a major discount in identification theft dangers stemming from SIM-swapping assaults and a decreased potential for governments to compel platforms to limit entry based mostly on customers’ nationalities. 

The commentary comes after Sign confirmed it’s exploring various signup pathways. Supply code references point out that the upcoming function, internally labeled “Sign Login,” will stay elective and would require a one-time cost fairly than a recurring subscription, with the charge designed to discourage spam and abuse whereas serving to fund the non-profit group’s operations. 

Though Vitalik Buterin acknowledged that eliminating the telephone quantity requirement represents a marked enchancment over the established order, he cautioned that the development doesn’t, in itself, resolve the deeper privateness vulnerabilities inherent in fashionable digital communication.

The Limits of Pseudonymity in an Age of AI Inference

Ethereum co-founder argued that pseudonymity—the apply of sustaining persistent accounts disconnected from real-world identities—has grow to be a “useless idea” in 2026, as customers repeatedly leak figuring out metadata via message timing, contact graphs, communication frequency, and behavioural patterns that subtle synthetic intelligence programs can correlate and piece collectively. 

As an instance the hierarchy of privateness protections, he offered a taxonomy starting from full publicity to superb unlinkability, noting that whereas Sign’s end-to-end encryption already ensures confidentiality by shielding message contents from third events, real anonymity calls for “message-by-message unlinkability,” whereby no observer can decide sender-receiver pairs and even determine particular person individuals. 

He recognized mixnet-based architectures and newer protocols resembling Session and SimpleX Chat as tasks actively pursuing this commonplace. Nevertheless, he highlighted spam and denial-of-service safety because the crucial remaining barrier, drawing a parallel to the widespread blocking of Tor exit nodes by providers making an attempt to mitigate abuse. He pointed to rising cryptographic approaches for establishing non-spammer credentials with out sacrificing unlinkability. 

Vitalik Buterin concluded by urging the privateness neighborhood to deal with phone-number-free registration as an essential milestone fairly than a remaining vacation spot, whereas persevering with to advance information leakage minimization. He additionally famous studies that Sign’s deliberate cost mechanism at present lacks a cryptocurrency choice, which may in any other case supply customers a further layer of economic privateness.
